Abstract (en)
A method of detecting slag in a molten steel flow includes an image capturing step of sequentially capturing a molten steel flow which is directed from a converter toward a ladle and includes molten steel and slag to acquire a plurality of captured images of the molten steel flow, a histogram creation step of creating a histogram for each captured image, a maximum peak point detection step of detecting a maximum peak point, in which the number of pixels is an absolute maximum value, for each histogram, and a maximum peak point type determination step of determining to which of the slag or the molten steel the maximum peak point of each histogram corresponds.
